Lost Pass phrase to Bitcoin Qt wallet. Help appreciated. technical question?

[MrCrabs]

Hi everybody,
I have a qt wallet with some coins in it.
I have a very long pass phrase.
85 characters (I think)
Is there a limit on the amount of characters you can input on the Qt wallet?
IE. while I may have inputted 85 characters dose the wallet truncate to a lesser amount?
Regards and thanks.

Try variations on case and see if you have any keyboard keys which are not working well.  Maybe the 'e' of your keyboard is stuck, for example.
If so, a passphrase such as 'Here comes the sun' might become 'Hre comes the sun' or 'Hr coms th sun' and so on.

Make sure your keymap hasn't been changed, i.e. you entered the password with a en-GB keyboard map and are trying to enter it with an en-US keyboard map. Only really an issue with special characters. For example, a "@" on a UK keyboard becomes a ' " ' if I change the keyboard map to a US one.
